ADP10 – Air Pressure Switch (IP54)

Duomo (UK) Ltd

To comply with current British Standards it is a requirement to prove that mechanical ventilation systems are operating in commercial catering establishments.

The ADP10 air pressure switch is used to monitor positive, negative or differential air or flue gas pressure. Kit includes tubing and pitot connections.

Mini Switch Monitor

Apollo Fire Detectors Ltd

The Mini Switch Monitor is an interface within an entirely new housing. This allows the unit to be fitted onto a standard 35mm DIN-Rail (using a twist-click motion) or mounted within an enclosure, for example a manual call point.

It is designed to monitor the state of one or more single pole, volt-free contacts connected on a single pair of cables and to report the status to Apollo compatible analogue addressable control equipment.

DIN-Rail Switch Monitor

Apollo Fire Detectors Ltd

The DIN-Rail Switch Monitor is designed to monitor the state of one or more single pole, volt free contacts connected on a single pair of cables and to report the status to Apollo compatible analogue control equipment.

  • Four input states - 'normal', 'fault', 'pre-alarm' and 'alarm'
  • Two visible LEDs
  • Loop-powered

Mains Switching Input-Output Unit

DIN-Rail Interface Enclosure

Apollo Fire Detectors Ltd

DIN-Rail Interface Enclosures are available in two sizes and can be used for housing intrinsically safe (IS) barriers or DIN-Rail mounted interfaces.

A multi-purpose label that features a section for use with IS systems is supplied. For non-IS systems, the part referring to IS can simply be removed.

  • Allows multiple interfaces to be housed together
  • IP67 rated

DIN-Rail Dual Isolator

Apollo Fire Detectors Ltd

The DIN-Rail Dual Isolator provides two independent isolators which sense and isolate short circuits on Discovery and XP95 loops and spurs.
